Application md June 2,1906. Serial No. 319,811.

My invention relates to the class of motors in which I kerosene is used,either alone, or in .conjunction with improvementl upon the structureset forth in my concurrent'application Serial N o. 319,010 filed May 28,1906 in which provision is made for collecting the excess or liquid dripof the hydrocarbon injected into the mixing chamber.

The essential and distinguishing feature of my present inventionconsists in providing means whereby the excess or liquid drip thuscollected may be vaporized by heat and returned to the mixing chamberwith the airsupply, thereby disposing of, vand utilizing such excess ordrip in the most advantageous manner, since the vapor thereof, beingintroduced directly into the Supply' of incoming air before the latterenters the mixing chamber, is in a highly nascent condition, and readyfor instant combustion when mixed with the rest of the charge. I am alsoenabled by my present invention to utilize the excess of drip ofhydro-carbon thus collected as a means for effecting the preliminarystarting of the engine, or even to introduce a supplemental supply ofliquid hydro-carbon to be vaporized and used for the purpose ashereinafterfully set forth.

The invention consists primarily, in the use, inconl junction'with areceptacle for collecting and holding carbon into said receptacle when ncarbon.

temporarily such liquid drip or excess of hydro-earbon'of i suitablemeans, as a lamp orequivalent device, for heating said receptacle so asto vaporize the liquid hydro-carbon as before stated; and secondarilythe invention'con` sists in arranging said drip collecting receptacle indirect communication with the air supply conduit so that the vaporizedhydro-carbon is returned to the mixing chamber by the incoming airsupply; and `in providing means for introducing a supplemental supply ofliquid hydro- (iesired for thepurpose of charging the air supply withhydro-carbon vapor independent of the collection of excess or drip fromthe mixing chamber.

My invention also includes certain other details and combinationshereinafter described and claimed specically. Y

In the accompanying drawing, the figure represents a central verticalsectional elevation of the mixing chamber and upper portion of acylinder of a motor in connection with my means for vaporizing liquidhydro- P represents symbolically a piston within the cylinder C, theupper portion of which constitutes the combustion chamber into which thesuccessive charges of .trickle down the'screen e, and

Alower portion of the receptacle d.

hydro-carbon vapor and air are drawn through the inlet valve c, in theusual way, the valve being retained normally Cn its seat by the springe.

M is the mixing chamber consisting of the substantially horizontalsection m, and avertical extension m, in the lower portion of whichlatter the inlet valve .is seated. The hydro-carbon is introduced intothe mixing chamber through one or more injectors I, of any desiredconstruction'. Three are shown by way of illustration `in theaccompanying drawings, one, as the central one, for kerosene, and theothers for, say alcohol and naphtha respectively. Kerosene may of coursebe used, alone, and as my invention relates particularly to its use, Ishall hereinafter confine my description thereto.

The injected kerosene first encounters the primary screen a, heretoforeus'ed for breaking up and diffusing Y the jet. .The impetus with whichthe kerosene is injected carries it through. this primary screen a, intothe central space b, beyond where it is mixed with air admitted throughthe conduit D,-the portion of a charge of kerosene, if any, notvaporized but remaining in globular form being carried by its inertiaagainst the screen' e, covering the opening d, into the air conduit D'.

Atmospheric or compressed air may be used as may be found mostexpedient. The impinging of the globules of unreduced kerosene againstthe screen e, tends to breakthem up and disintegrate the oil so that itis in the best possible gondition to be takenv p and absorbed by theincoming current of air.

If there is an excess of liquid kerosene, some of it will percolate orbe precipitated through the screen c, and enter'the conduit D settlinginto the cup or pocket d and another portion of such unvaporized excesswill into the annular trough or receptacle f, from which it may be drawnoff, through a drain pipe f, and valve f 2. The annular oil reservoirf,may also beprovided with a pet or tell cock f 3, for ascertaining theoil levelithercin. Thus far I have described a structure which isIessentially the vsame as that vdisclosed in my concurrent applicationSerial No. 319,010 filed May 28th v1906, hereinbeforc referred to.

The distinguishing feature of my present invention consists in 'theprovision of means for heating and vaporizing any liquid hydrocarbonpresent in the Any convenient or well known means may be employed forthis purpose -the lamp L, indicated symbolically in the drawingsrepresenting any external means of applying heat to the lower portion ofthe said receptacle d. Provision may bemadefor permitting the dripcollected in the inner annular receptacle f, to flow into-the lowerportion of the external receptacle d, as by thechanncl f 4, the fluidhydro-carbon thus drained from the annular receptacle f,

taking the place of that vaporized by the -heat applied to the lower-portion of said `external receptacle d. The hydro-Carbonthus vaporizedwithin the receptacle cZ, rises and mingles with theair entering throughthe conduit D, and is carried by the air into the mixing Chamber, toAconibine with the fresh hydrocarbon injected into the latter. It willbe seen that I thus not only collect and eliminate all drip or excess ofhydro carbon and prevent its introduction in 4that forrninto thecombustion' chamber; but I also at the same time enrichen and rendiermore combustible the successive charges of hydro-carbon. In order nottobe dependent on the drip or exces of hydro-carbon above set forth Iprovide independent means for introducing liquid hydro-carbon into' theAexternal recept-ac led, as the pipe d2, and valve d3, so that theoperation of vaporizingthe oil and charging the inlet of air therewithmay be made continuous, if

desired. Furthermore this enables me to utilize,v this f device foreffecting the preliminary heating and vaporizing of the charges duringthe operation of starting the motor and before ,the mixing andcombustion cham bers have become thoroughly heated. Y

What I claimy as my invention, and desire to secure by Letters Patentis, 1. In a hydrocarbonimotor of the character designated,

- ,the combination of a mixing'chamber, a conduit for adL mitting air tosald'mixing-chamber,l a screen interposed between said air conduit andsaid mixing chamber, means` for injecting hydrocarbon into said mixingchamber and against said screen. a drip collecting receptacle below andforming ay continuation of said Aair conduit, and external .against'saidscreen, a drip-collecting receptacle below and forming a continuation ofsaid'air conduit, means for introducing a preliminary s upply ofhydrocarbon to said drip collectingchamber for` use in effecting thepreliminary starting Aof the motor, and external means for heatlng thehydro-,carbon in said drip'collecting chamber whereby the saidhydrocarbon isvaporized and caused supplied thereto, for the purpose toenter 'the mixing chamber with the air supplied thereto,
